Abstract :

X–ray flux using lead shielded scintillation counter for the month of September 2000. The scintillation counter pointing towards Moon detected secondary cosmic ray flux and SEP (Solar cosmic ray ) mostly gamma rays and X–ray approaching on surface of the Earth. We observed variation in secondary cosmic gamma ray flux (SCGR flux), X– ray flux and variation of secondary cosmic gamma ray flux at some energy in energy spectrum. During the passage of Moon through background of Uranus and Capricornus constellation we observed aupt change in energy spectra on 9th and 10th September, 2000. In the course of observation two prominent peaks in energy spectrum showed systematic variation in position from 1.18 MeV to 3.34 MeV and in count rate from 40 to 150–counts/ 30 min. During Phases of moon experimental study these results of variation of SCGR flux, energy and X Ray flux can be explained by different relative location of Moon with regards to the Sun
